Abstract
The utility model is related to carbon fibers to have an area of multiple tube, including drum arc, knuckle, transition line and the positive round windowing of drum body, hollow circle drum section of the bulging arc for the carbon fiber square tube, the transition line is the pipe transitional straight section that two parallel plane butts are formed up and down, the knuckle is connect for the bulging arc with the rounded corner rounding off of the transition line, and the bulging body positive round windowing hits exactly the circular hole of stringcourse to be located at the bulging arc.The carbon fiber circumference multiple tube of the utility model, circle drum body and rectangular line segment round-corner transition, if drum body just opens a window, carbon fiber structural intensity is high, durable, and rational in infrastructure simple, synthesis is cost-effective.
Description
Technical field
The utility model is related to Carbon Fiber Technology fields, particularly composite fibre square tube.
Background technology
In some marine engineerings, needing to use circumference multiple tube, the circumference multiple tube of the prior art is made of plastic cement,
Intensity difference, windowing fluffing cause fraction defective high, and easily cracking causes breakage to transition face.
Utility model content
Based on this, for the prior art, the technical problem to be solved of the utility model is just to provide a kind of structure letter
Single, at low cost, rounding off high intensity carbon fiber has an area of multiple tube.
The technical solution of the utility model is：
A kind of carbon fiber has an area of multiple tube, including drum arc, knuckle, transition line and the positive round windowing of drum body, the drum
Hollow circle drum section of the arc for the carbon fiber square tube, the transition line is the pipe transition that two parallel plane butts are formed up and down
Straightway, the knuckle are connect for the bulging arc with the rounded corner rounding off of the transition line, the bulging body positive round
It opens a window and the circular hole of stringcourse is hit exactly to be located at the bulging arc.
The bulging arc includes external drum arc and interior bulging arc in one of the embodiments,.
The transition line includes line segment in the outer line segment of transition and transition in one of the embodiments,.
The knuckle includes transition bull nose and transition filleted corner in one of the embodiments, outside the transition
Fillet connects the big rounded corner of the outer line segment of the transition for the external drum arc, and the transition filleted corner rouses connection institute for the inner arc
State the small rounded corner of line segment in transition.
The bulging body positive round windowing is located at the two of one end of the carbon fiber circumference multiple tube in one of the embodiments,
Rouse body in side.
The bulging body positive round windowing quantity is 2 in one of the embodiments,.
Compared with the prior art, the carbon fiber circumference multiple tube of the utility model, circle drum body and rectangular line segment round-corner transition, if
Drum body just opens a window, and carbon fiber structural intensity is high, durable, and rational in infrastructure simple, synthesis is cost-effective.
Description of the drawings
Fig. 1 is that the carbon fiber of the utility model has an area of the structural front view of multiple tube；
Fig. 2 is that the carbon fiber of the utility model has an area of the structure left view of multiple tube.
In figure, 10-- drum arcs；11-- external drum arcs；Drum arc in 12--；20-- knuckles；21-- transition bull noses；22--
Transition filleted corner；30-- transition lines；The outer line segment of 31-- transition；Line segment in 32-- transition；40-- drum body positive round windowings.
Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.It should be noted that not rushing
In the case of prominent, the feature in following embodiment and embodiment can be combined with each other.
Fig. 1 gives the carbon fiber circumference composite pipe structure schematic diagram of the utility model, as seen from the figure, carbon fiber circumference
Multiple tube, including drum arc 10, knuckle 20, transition line 30 and drum body positive round windowing 40, drum arc 10 is carbon fiber square tube
Hollow circle drum section, transition line 30 are the pipe transitional straight section that two parallel plane butts are formed up and down, and knuckle 30 is drum
Arc 10 is connect with the rounded corner rounding off of transition line 30, and drum body positive round windowing 40 is to be located at the circle that bulging arc 10 hits exactly stringcourse
Hole.
Drum arc 10 includes external drum arc 11 and interior bulging arc 12.Transition line 30 includes line segment in the outer line segment 31 of transition and transition
32.Knuckle 20 includes transition bull nose 21 and transition filleted corner 22, and transition bull nose 21 is connected for external drum arc 11 outside transition
The big rounded corner of line segment 31, transition filleted corner 22 connect the small rounded corner of line segment 32 in transition for inner arc drum 12.
Drum body positive round windowing 40 is located at the both sides drum body of one end of carbon fiber circumference multiple tube.Drum body positive round 40 quantity of windowing
It is 2.
From the above, it may be appreciated that the carbon fiber circumference multiple tube of the utility model, circle drum body and rectangular line segment round-corner transition, if drum
Body just opens a window, and carbon fiber structural intensity is high, durable, and rational in infrastructure simple, synthesis is cost-effective.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed,
But it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
